Write Everything Twice (WET)

A humorous backronym used to describe code that violates the DRY principle by duplicating logic or knowledge in multiple places. The term was coined as a contrast to DRY and is sometimes expanded as "Write Every Time" or "We Enjoy Typing." 

During this episode it was independently coined live in the chat: "You want DRY feet, not WET feet." WET code is harder to maintain because a single change in business logic must be tracked down and repeated in every location where it appears.
